Top 10 Infrared Thermometers with AliExpress

Infrared thermometers can remotely measure the temperature of any object. The device responds to thermal radiation. The second name of the device is the pyrometer (from the Greek. "Fire" and "measure"). The principle of operation is based on the capture of electromagnetic waves in the infrared range. After measuring their length, the signal is transmitted to the detector, which converts the received data into a digital value. The models presented on the site of AliExpress are usually equipped with a laser. Its beam serves only to indicate the target, but not for temperature measurements.

Infrared thermometers are larger in size than the usual mercury or alcohol models, commonly called thermometers. They are shaped like pistols with an LCD screen. The equipment measures the temperature without contact, but there are variations that require short-term contact with the body.

In order to choose the best IR thermometer, you need to consider the following data:

• range of temperatures studied - when working in a narrow range, it makes no sense to buy expensive models;
• working distance (DS sighting factor) - DS 12: 1 means that the model's working distance is up to 5 meters, DS 20: 1 is about 10 meters;
• emission factor - means the ability of the device to read the amount of reflected heat (there are models with adjustable and fixed coefficient), by default it is 0.95 (suitable for most materials);
• type of laser - in budget models it has one point and shows only the center of measurement, two lasers more accurately demonstrate the area of ​​measurements;
• a way to reflect the information received - simple models equip an LCD screen, more complex ones can be connected to a computer.

In the top 10 are the best models for domestic and industrial use. The main criteria for getting into the steel rating are:

• functionality;
• compliance with price quality;
• build quality;
• reviews and ratings of the AliExpress customers.

The best infrared thermometers for domestic use

In everyday life, non-contact IR thermometers are used to detect heat leaks, to study the insulation of pipes and the tightness of windows. They are needed during repair work, in the kitchen for cooking, when diagnosing the condition of the car. Often such equipment has additional functions: backlighting, built-in memory, holding indicators on the screen. The most inexpensive Chinese models can only measure temperature. However, they are characterized by good accuracy. Therefore, the category includes both low-cost infrared thermometers and goods in the middle price category.

4 DEKOPRO WD01

This measuring device is bought by housewives for contactless control of the temperature of dishes, and by a master for auto repair. And also electricians, sportsmen - the list goes on. The only thing for which it is not suitable is to measure body temperature. But with other objects infrared thermometer works correctly.Many buyers with AliExpress are sure that it is one of the most accurate in its segment. Thermometer perfectly measures the temperature at a distance of 5 meters to the object.

The seller has the product in 4 versions. The more expensive the model, the wider its temperature range and richer functionality. There is a function of storing the minimum and maximum values ​​of measurements, turning off the backlight and laser pointer. Of the minuses mentioned in the reviews, we can note the inaccuracy of the laser pointer. But it is rather a feature of this model. With manual aiming such flaws are not detected.

The equipment is well thought out design. The display is large, informative. There is an automatic shutdown function after 30 seconds of inactivity. On the accuracy of measurements it is one of the best models. If necessary, it can be calibrated. The site has a pyrometer in 3 versions - a remote thermometer with a measuring range of -50 to +380 degrees, a device measuring temperature ranging from -50 to +550 degrees, and the same model with a hygrometer.

1 SmartSensor AT380 / AT380 +

A simple infrared thermometer for everyday home use. The measurement error is about 2 degrees, which corresponds to the data declared by the seller. The measurement ceiling is +380 degrees. The device works fine in the cold - the minimum temperature is -32 degrees. The thermometer is equipped with a powerful laser pointer, which is visible far away. But to obtain correct measurement results, it is not necessary to carry out at a distance of more than 5 meters.

The model non-contact reads the thermal radiation of objects with an emission coefficient of 0.95 (wood, paper, water, plastic, rubber, glass). Note that when working it is important to change the battery in time. If she “sits down”, the thermometer will show inaccurate data. The product reviews are positive, they are actively buying it on AliExpress.

The best industrial infrared thermometers (pyrometers)

This is a whole group of infrared thermometers that measure thermal radiation in the infrared spectrum. Use them in those cases if the contact measurement of temperature is complicated. Usually they are equipped with laser pointers for precise aiming. The pyrometer is used in metallurgy, food industry, plastics production, diagnostic work and equipment maintenance.
